Tree Bylaw

A permit is mandatory when an owner of land within the intervention zone wants to cut down a tree with a diameter of more than 10 cm.

A permit for trees may also be required for construction, development, or subdivision requests in order to take into account the trees present or to calculate the necessary replanting.

• Trees posing an immediate hazard, with supporting evidence
• Trees on Crown land (i.e., land owned by the provincial or federal government)
• Trees in orchards, maple groves and nurseries
• Trees that fall under the purview of service providers (e.g., NB Power)
• Trees under 10 cm in diameter (except for newly planted trees)

Start your permit request by sending an email to enviro@dieppe.ca. A city employee will contact you to schedule a visit to evaluate the tree(s) and confirm whether additional information is required, such as plans, drawings, consent from neighbouring owners if the tree is on a property line, etc. Depending on the complexity of the project, an application can take up to 20 working days to complete, so it’s important to plan ahead to avoid delays. Trees will be evaluated on a first-come, first-served basis. If your project is urgent, you can submit a tree study carried out at your own expense, provided it was done by a certified arborist. A guide is available here.

The cost of a permit to cut healthy trees is $35 plus $100 per hectare of land to be assessed. For a project located on a 10-hectare lot, for example, the total cost would be $1,035, or $35 + $1,000. The fee includes the cost of the tree study, internal analyses, recommendations and the permit itself.

There is no charge for dead, seriously diseased or hazardous trees, but a permit is still required.

Fees cover only part of the administrative costs of the process. In many cities that have a tree bylaw, applicants must pay for their own tree studies, at an average cost of $250. The City has decided to cover those costs to ease the transition to the new bylaw and help residents take good care of our trees.

No. It’s a way to ensure a sustainable future for our community and maintain the quality of life that Dieppe residents enjoy.
The fees collected for lost trees or for security deposits will be used to pay for municipal planting projects and increase the number of trees in the city.

Yes, but no fee will be charged.

Yes. If a tree poses an immediate danger, you can cut it down, but you must apply for a permit afterwards and demonstrate that the tree did in fact pose a hazard, with supporting evidence like photos, an arborist’s report, and so on. However, no fee will be charged.

Yes, but no fee will be charged.

Yes. An arborist must confirm the identity of the tree and the risk it poses to the environment or structures. However, no fee will be charged.

Yes. Permission will only be granted if a building permit is issued by the municipality. The tree study should be carried out as early as possible in the process. Landowners will be required to compensate for lost trees by planting new ones or by contributing financially to replanting initiatives elsewhere in the city if replanting was not an option on their property.

Yes. To protect our trees and ensure a sustainable future, the City can refuse to allow cutting for reasons deemed invalid.

Yes, for major pruning, i.e., cutting off more than 25% of the living branches, which can seriously damage a tree’s health if not done properly. A municipal employee can advise you on how to best ensure the tree’s survival. An owner who inflicts excessive damage on a tree or causes its death, without a permit, may be fined.

Our staff can help you select the right tree and best site for your needs. It’s preferable to use native species, i.e., trees that already grow naturally in the region and are adapted to our climate. Selection tools based on site conditions are also available online (https://www.greeningcanadianlandscape.ca/tree-species-selector/eastern-canada-tree-species).  

• White spruce (Picea glauca)
• Norway spruce (Picea abies)
• Black spruce (Picea mariana)
• Red spruce (Picea rubens)
• Tamarack (Larix laricina)
• White pine (Pinus strobus)
• Red pine (Pinus resinosa)
• Pine (Pinus sp.)
• Balsam fir (Abies balsamea)
• Northern white cedar (Thuja occidentalis)
• Paper birch (Betula papyrifera)
• Yellow birch (Betula alleghaniensis)
• Sugar maple (Acer saccharum)
• Red maple (Acer rubrum)
• American beech (Fagus grandifolia)
• Horticultural specimens submitted for approval

A $500 fee per tree not planted will be charged, to help fund replanting initiatives elsewhere in the city.

You can also plant a tree on another property. Pre-approval from the City is required.

Our city’s forest is made up of all the trees found in Dieppe, including those on municipal and private land. Research shows that much of the biodiversity of urban trees is found on private land, and there is a greater variety of tree sizes on private properties than on streets and in public spaces. Hence, all trees need to be protected.

Furthermore, if a developer is required to preserve trees on land being developed, it makes no sense to then allow the owner buying that land to cut down those trees without authorization.

Yes. Depending on the tree(s) in question and the conditions of the project, the City may either prohibit the cutting of certain trees, authorize cutting with a replanting condition, or authorize cutting with no conditions. Each project and tree will be assessed by qualified municipal staff.

Some trees are subject to protection under provincial and federal laws, which is why a tree study is important from the outset.

Trees on municipal land, such as trails, parks and woodlands, are protected from cutting wherever possible.
Finally, the protection of wetlands or the presence of nesting birds or protected animal species justifies a ban on cutting until appropriate measures are in place.

Buffer zones are not always the best choice for tree conservation. Tree studies enable us to assess the conditions of a given site before proposing conservation measures, thereby avoiding problems for future occupants. For example, requiring a strip of declining trees such as poplar and birch, which don’t have the same life expectancy as maples, can lead to problems, as well as significant hazards and costs.

The municipalities we consulted noted certain problems with imposing that particular condition. Street-facing trees may be required, but it depends on the project.

Studies show that 80% of Canadians live in urban centres and it will be those people who are most at risk from heat waves. Efforts therefore need to be focussed on protecting trees in urban settings. However, we are considering ways to better regulate tree-cutting in rural areas and outside the urban perimeter, but this will come later.

It is worth pointing out that tree-cutting in rural areas must still be declared to the City, under penalty of fine, so that we can document the practice and better assess future needs.

It all depends on existing site conditions. Factors such as slope, elevation and soil composition must be considered when drawing up a drainage plan. Tree conservation is generally possible, and the consultants who carry out drainage studies are qualified to include trees in their calculations. Generally speaking, keeping trees improves water retention and can therefore reduce drainage and retention requirements. Each project will be assessed based on this information.
